Answer:
y = 17*(3)ˣ 
Step-by-step explanation:
y=abˣ
(0,17) : 17 = a*b⁰ = a
(2,153) : 153 = a*b² = 17*b²
b² = 153/17 = 9
b = ± 3  ... (0,17) and (2,153) in first quadrant   b = 3
function: y = 17*(3)ˣ 
 
        
             
        
        
        
Answer:

Let's assume 
point K as (x,y)
M is the midpoint of JK
so, other point as J(0, 11) 
M(-3,2)

now, we can compare both sides 
Calculation of x-coordinate:
we get 


Calculation of y-coordinate:
we get 



so, we will get point K 
K=(-6,-7)............Answer
